Concord, New Hampshire (CNN) - The New Hampshire secretary of state will end a month of tense speculation and maneuvering next week when he announces the date for the state's primary.

Bill Gardner plans to announce the first-in-the-nation primary date after the filing period for candidates is over. The filing period ends Friday.
Gardner is widely expected to announce a primary date of Jan. 10, which would put New Hampshire's contest a week after the Iowa caucus on Jan. 3.

Earlier this month Gardner had said the primary could be held in early December unless Nevada's GOP pushed back its caucus date.

On Saturday Nevada Republicans bowed to pressure and set their new caucus date for Feb. 4.

Former House Speaker Newt Gingrich will file his candidacy paperwork in New Hampshire Tuesday afternoon. Texas Gov. Rick Perry plans to file on Friday.
